@Albee_Freeoneday, what makes you think...
...that trains will free us from "the humiliating and worthless
hassles of the TSA"?
Do notice that the name of the wonderful government
organization your refer to is the "Transportation Security
Administration". The first word is "transportation", as in not just
limited to "air transportation". Anyone who thinks that travel by
rail will be ignored by terrorists or ever expanding government
security agencies is delusional. It's inevitable that boarding a
high-speed train will be just as annoying as boarding an airline
flight.
